ELEOTRiC HORN.

- Specification of Letters Patent.

Patented April 30, 1:407.

Application filed June 23.1906. Serial No. 323.961.

To all whom it may concern:

Be it known that I, Iinxar (.saxrr, a subject of the King of'Hunga-ry, and a resident of Orange, Essex county, New Jersey, have invented certain new and useful 1m prove- -1nents in Electric Horns, oi which the following is a specification.

My invention relates to electric horns to be usedior signaling purposes, for instance on automobiles.

The object of my invention is to provide a very sim le and e'l'iicient device of the aboveindicate class.

Reference is to be had to the accompanying drawings in which Figure 1 is a longitudinal section, (on line 11 of Fig. 2) of a horn embodying my in vention, and Fig. 2 is a top view thereof, with parts broken away.

A is the casing of the horn, preferably provided with openings A in its rear end wall. Into the open front end of this casing is fitted the cylindrical flange B of the funnel-shaped mouth-piece B from which the sound issues. This flange may be held simply by friction, or it may be more securely fastened by soldering or otherwise. Within the casing is located a U-shaped arm or carrier C,-the ends of which as shown may come up on the inside of the-flange B and be secured thereto by screws 1) the heads of which are received in notches A at the forward edge of the casing A. \Vithin the cover or 'H'lOUilPplOCQ B a metal ring E is arranged, with washers F, and a diaphragm G between the washers. Screws H secure the ring, washers and diaphragm together, but these screws should not touch the diaphragm, so that the latter will be insulated by the wasl'iers F. The diaphragm carries a spring 1 adapted. to term a circuit-breaker in conjunction with a screw J on the mouth-piece B or other stationary part of the apparatus. An. armature K is also attached to the diaphragm G, and faces the poles of the electro-magnet L, secured to the carrier (.7. The wire coils of the electroinagnet are connected at one end with the diaphragm, as shown at G, and at the other end with a binding screw M, carried by the back of the casing A, but insulate 5 iiitl'z" from. The terminals of the battery or other source of electric current are connected with the screws J and M respectively. The wire shown attached to the screw J might be his tened instead to abinding screw on the back of the casing A.

in operation, as the current is turned on by means of a suitable switch of any approved magnet ii, thus attracting the armature ii.

ire-magnet but does not at once interrupt the contact between the sprmg i and the screw: J,

Only when the armature K has moved inward a predetermined distance, the spring I will come out of contact with the screw J so as to break the circuit. The moment this happens, the magnet L will no longer attract the armature and the diaphragm will swing back whereby the circuit is again closed, and this operation is repeated in quick succession.

The vibrations of the diaphragm G produce a sound which is condensed and conveyed to the outside by the tapering mouthpiece B. The apertures A of the casing are provided in order to allow the air within the casing to freely respond to the vibrations of the diaphragm, since a body of inclosed air would tend to damp the vibrations. The use of a spring contact in connection with the diaphragm enables me to secure a much more reliable action than if the screw B engaged the diaphragm directly.

The apparatus might operate without the use of a separate armature K if the diaphragm is made of a magnetic material, but even when such material is used for the diaphragm, i prefer to secure a separate armature thereto, thus attaining a more eilicient action.

I claim:

1. An electric horn comprising a casing with apertures in its rear end, a tapering mouthiece at the front end of said casing, a. U-shaped carrier located within the casing, an electro-inagnet supported by said carrier, a diaphragm located between said electromagnet and the outlet of 1h mouth-piece, spring carried by the diaphragm on the outlet side thereof, an armature carried by the opposite side of the diaphragm, a contact screw adapted to engage said, spring, and electrical connections for causing the circuitof the electro-magnet to be closed and broken 'us the diaphragm vibrates under the inlluonce of the elcctro-1nagnet.

2. An electric horn comprising a casing provided with an outlet for the escape of sound, anelectro-magnet within said casing, a diaphragm located between the outlet and a the electro-magnet, a spring carried by the style, the current would energize the electrothe spring being normally undertension,

This brings the diaphragm G toward-the elechaving an outletfor the escape of sound, an electro-megnet within said casing, a (ll-ii-- phragm between the outlet and the electro magnet, an armature and a spring carried by said diaphragm, a Contact member engaging the spring, and electrical connections for causing-the circuit of the electro-magnet to be ,oioseil and broken as the diaphragm Vi brates. I I 4. A11 electric horn comprising a casing provided with an outlet fo1 the escape of sound, an electro-magnet in said oasing, it

Contact member engaging the l phragm,

diaphragm located hetii een the said outlet and the eleetro magiit; an armature secured to the diaphragm on the side facing the electromagnet, a spring secured to the diaphragm on the-opposite side, a contact member gaging said spring, a connection ii'oi'n one of the arn'iaiture coils to the die and a binding screw connected with the other end of the eleotro-magnet coils.

in testimony whereof, l have hereunto signed my name in the presence of two subscribing Witnesses.
